READING- SPIKES.

Specification of Letters Patent No.

To all whom it may concern Be it known that I, ELISI-IA H. COLLIER, of Scituate, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in the Anvils and Die-Plates Used for Heading Spikes, &c., and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may be distinguished from others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.

The figures of the accompanying plate of drawings represent my improvements. Figure 1 is a plan or top view of my improved anvil, or die plate. Fig. 2 is a central vertical section of the same.

My improvements are made upon the anvils or die plates in which spikes, nails, &o., are headed by hand labor, and consist in hanging the plate or anvil, upon centers, in such a manner that it can be reversed, that is, its under side brought uppermost, and in forming a double set of die holes in the plate. By this arrangement, after the point-- ed blanks are fed into one set of die holes, and headed, the plate is reversed, and the other set of die holes fitted with blanks, which are headed in asimilar manner, the blanks first headed, in the meantime, dropping out of the die holes by their own 14,088, dated January 15, 1856.

The plate a a is supported in a horizontal position by two sustaining bars, d, (Z. 6, e, &c., are the first set of die holes into which the pointed blanks are fed, and then headed by the workman. The sustaining bars (Z, (Z are then drawn out, and the plate a a reversed, so as to bring its under face uppermost by means of a winch The sustaining bars 4, d are then replaced, and the second set of die holes 9, g, &c., filled with blanks, that are headed in the same manner as before. The first set of blanks that have been headed, will, while the second set are being headed, cool and shrink sufliciently to drop out by their own weight.

Having thus described my improvements I shall state my claims as follows:

What I claim as my invention and desire to have secured to me by Letters Patent is Hanging the die plate or anvil upon centers or bearings in such a manner that it can be reversed, or its under face brought uppermost, the said die plate or anvil being provided with a double set of die holes, as described, and for the purpose specified.
